It's flat -- a nice blend to the frame. I bought one once sight unseen and it was rounded, like a bubble. Don't want that, so I was looking for something that's the same contour, but un-branded.

The more I look at it, the less it bothers me, but if you're not bothered by something like this, you have no idea what it is to be bothered by it. I like clean finishes too, which rubs "finish character" guys wrong way. Vive la difference.
